TOOL HANDLE.

Application filed August 23,1926. Serial No. 130,881.

This invention relates to D-handles for. shovels and the like. i

The chief object of the inventionis to provide a D-handle of wood and metal, prefer-' ably steel, which is not only adapted to take the loads and shocks to be sustained in use but will fit the hand in all positions in such fashion that it'will give the greatest comfort with the least fatigue and which will have the proper balance, and which furthermore will have its parts so arranged that the metallic portions are shielded preventing rusting and wood decay.

The chief feature of the invention consists in the accomplishment of the foregoing'object by the utilization of a combination wood and steel handle which has a cantilever action when subjected to strain and which has its parts so arranged together that the re-. sultant handle has all the necessary strength, balance and comfort of the old wooden D- handle.

The full nature of the invention will be understood from the accompanying drawings and the following description and claims:

In the drawings Fig. 1. is an elevational view with a part shown in quartered and longitudinal section. Fig. 2 is a longitudinal sectional view taken on line 22 of Fig.1 and in the direction of the arrows. Fig. 3 is a top plan view of the ferrule.

In the drawings 10 indicates the stale of a fork or shovel or the like which is reduced at 11 and is further reduced at 12 and incurved orarcua-te as shown in Figs. 1 and 2.

Said grip includes a central bolt opening 18 extending therethrough and each end of the grip is reduced annularly as at 19 and is further provided with a transverse slot 20 which, just beneath the intersection with the opening 18, is extended inwardly and angularly as at 21.

A substantially U-shaped cover 22 is provided on its opposite parallel edges-with a if lJ-shaped groove 23 and said U-shaped cover 1s also arcuate in outline as indicated at 24. Said U-shaped cover bears upon the cap portion of the ferrule and is weldedtothe lugs or projecting portions 16 of said ferrule. The upper ends of the U-shaped cover'are identical but oppositely positioned and each includes an outwardly and upwardly inclined portion 25 and a parallel extension 26, the latter being apertured to receive bolt 27. The strap portion 26 is receivable by the groove 20 and the wedging portion 25 is receivable by the inclined portion 21 of said groove. The U-shaped member 22 thus forms the inside of the D -portion of the handle. The exteriororbody portion of the D-handle comprises a yoke forming member,

which includes a semicircular arm portionv 30 apertured at 31 to register with the openmg 32 receivingthe rivet 33, whereby the body of the handle is anchored to the stale 10 and in Deformation with the semi-circular portions 30 embracing the reduced portion 11 of said stale. 7 Each fork extension of the yoke is substantially U-shaped in cross section throughout its length and extends outwardly and upwardly,the depth'of the U decreasing toward the free ends. -;The upper opposite edges of the yoke, herein indicated by the numeral 34, are receivable by the groove 23 substantially throughout the curvature and thus the cover 22 covers the trough formed by said U-shaped portions, and also serves as a retainer and moisture protector.

Each upper free end 35 is apertured for registration with the aperture of, the strap and the opening in the grip so that the'rivet 27 will extend through all of heforegoing and rigidly anchor the aforesaid in unitary arrangement. When thus anchored the. grip exerts a wedging action on the inclined portion 25 and causes the cover- 22 towedgingly engageor bear upon the upper edges of the U-shaped body portion of the handle. The upper end of each of said U-shaped body members is formed into a substantially circular cup 36 which is receivableby the reduced grooved end 19 of the grip 17. The

handle and arranged so that it will give the greatestcomfort with the least fatigue to the user thereof. 7

When downward pressure is applied to point B, the tendency for said rivet and associated parts is to swing in an are from a center at the bearing cap, but this movement is resisted by the rigidity of the yoke members forming the body which are riveted to the stale and locked to the cover 22 throughout their length by the U-shaped seams 23. 'Any tendency of the U-shaped cover towards" movement from the central planeis resisted by the engagement of said coverwith the upper edges 34 of the yoke or body, said'resistance being obtained through the envelop'ment of the end of the stale and through the anchorage thereto by rivet 32. When a side thrust is applied at point B, on the handle it acts as a cantilever for this pressure tends to thrust one arm of the cover 22fanchored' to the rivet 27 down against the ferrule sup orted by the end of ovement is resisted by the welded connection therewith and thus the cover isu'nder compression and the same tends to force outwardly that portion adjacent the anchorage at, rivet 27." Suchtendency is prevented by the yoke or body which with a similar median parting line.

is subjected to a tension force, thus affecting or completim cantilever action. Simultaneously "therewith in the lower half of the D- handle the stresses are reversed in the cover and the yoke and also each of the yoke and cover portions adjacent thereto support or divide the load.

The cover 22 and the ferrule take the shock when the shovel is used and as the yokes are in one piece there is no separation strain at the median line of the enclosing portion surrounding the end of the stale, whichse'pa-ration is a common weakness of other metallic yokes made in two piecesTfir e present arrangementin addition to eliminating thiswe'akness, also includes sufficient spring in the metal by reason of the shape of the parts to obtain the desired fiexlbility in: this t pe of handle. v

It wil be apparent from the foregoing description relative to the anchorage of the free ends of-the' cover and the'yoke that the cooperating relationship is such with the grip handle that a'wedging and non-rotative mounting is obtained. The particular arrangement of the cover 22- is such that 1t gives greater clearance in the lower part of the eye of the D and also as constructed gives greater-strength t'o'the base of the D and P gives resiliency to that portion of thegcover mounting the sired.
